Vite app shows blank page with embeded backend mern

[Vishal_Torne]

Hello render community, I have created a reactjs app with nodejs backend and mongodb. I was able to deploy the backend which embedded in my root folder and it does not have a separate frontend folder. Backend successfully provides the data from db. I have checked the routes except “/” which gives cannot get / error.

So I am using a static site using render titled shoppe-globe and other one for backend using webservices titled shoppe-globe-app for backend from the same repo to connect my backend and display react pages. When i deploy static website it shows blank page and not errors. Any suggestion about this.
I am pasting my folder structure and package.json file in the root
folder structure is like this

Shoppe_Globe_App

• backend
• node_modules
• public
• src
• git_ignore
• eslint.config.js
• index.html
• package-lock.json
• package.json
• vite.config.json
